Steps:

  1. Draw BC = 6 cm.

  2. At B, construct ∠EBC = 90° and at C, construct ∠FCB = 120°.

  3. From EB cut AB = 6 cm and from FC cut DC = 6 cm.

  4. Join A and D.

Construct a quadrilateral ABCD, such that AB = BC = CD = 6 cm, ∠B = 90° and ∠C = 120°. Constructions, Concise Mathematics Solutions ICSE Class 8.
